Overview
SIST EN ISO 52909:2024 provides supplementary guidelines for evaluating the mechanical properties of metal parts produced by additive manufacturing (AM), with a specific focus on how the orientation and location within the build volume affect these properties. Issued by CEN and aligned with international standards, this document supports industry needs by guiding the reporting and interpretation of test results for both as-built specimens and samples cut from additively manufactured components. The standard aims to enable reliable, transparent, and comparable data to support part qualification, process optimization, and quality assurance across various sectors using metal AM.
Key Topics
-
Mechanical Property Evaluation in AM Metals
Guidance is provided for both static/quasi-static and dynamic mechanical testing of metallic parts produced by AM, including tensile, compression, fracture toughness, and fatigue testing.
-
Orientation and Location Dependence
The standard outlines how the mechanical properties of AM metal parts are influenced by their position (x, y, z build coordinates) and orientation within the build envelope, ensuring accurate reporting and performance assessment.
-
Terminology Consistency
Utilizes and expands upon the coordinate systems and nomenclature introduced in ISO/ASTM 52900 and ISO 17295 to address AM-specific requirements for geometry, orientation, and specimen extraction.
-
Test Methods and Reporting
Recommends direct part testing where feasible, and provides principles for preparing and reporting on cut-out or miniaturized specimens, including the need for clear description of specimen extraction relative to original part geometry.
-
Influence of Process Parameters
Emphasizes the importance of documenting scan strategies, AM process variables, and post-processing treatments, all of which may significantly impact mechanical performance.
Applications
SIST EN ISO 52909:2024 is a vital resource for:
-
Manufacturers and Service Providers
Ensuring the mechanical integrity of metal AM parts by establishing best practices for specimen extraction, testing, and reporting to meet customer and regulatory demands.
-
Quality Assurance and Certification
Supporting traceable and consistent characterization of materials for certification, qualification, and validation within industries such as aerospace, automotive, medical devices, and industrial tooling.
-
Research and Development
Enabling material scientists and engineers to investigate the local and directional variability in mechanical properties resulting from different AM processes and design approaches.
-
Process Development and Optimization
Utilizing orientation- and location-specific data to refine process parameters, minimize defects, and improve the reliability of metal AM components.
